of the system is decreased at constant temperature. 1)The relative concentrations of each gas must change. 2)The concentration of each gas will increase. 3) The relative concentrations of each gas must remain constant. 4)The concentration of each gas will not change.

Answer:

3) The relative concentrations of each gas must remain constant.

4)The concentration of each gas will not change.

Explanation:

  • For the equilibrium system:

<em>X₂ + Y₂ ⇄ 2XY,</em>

The no. of moles of gases in each side is constant; there is 2 moles of gases at reactants side and 2 moles of gases at products side.

So, changing the volume will not affect on the equilibrium system.

<em>So, the right choice is:</em>

3) The relative concentrations of each gas must remain constant.

4)The concentration of each gas will not change.

Which formula can be used to calculate the theoretical yield? (5 points)
Semenov [28]

Answer:

Multiply the number of moles in the product by the molecular weight of the product to determine the theoretical yield.

Explanation:

For example:

If you created 0.5 moles of Aluminium Oxide the molecular weight of Aluminium Oxide is 101.96g/mole, so you would get 50.98g as the theoretical yield.

So multiply,..

101.96x0.5= 50.98

This is the correct way to calculate the theoretical yield

22. Which one of the following processes has a negative value for AH°?
ss7ja [257]

Answer:

C

Explanation:

A negative deltaH means that the reaction has to give up heat in order to happen. You have to treat deltaH as a reactant. So the question is do you need to add heat to the reactants to make the products. If you do, deltaH is plus.

Heat is required to make a solid go to a gas. deltaH is plus. A is not the answer.

A lot of heat is required for B (something like 400 Kj / mole. Like A, deltaH is plus and B is not the answer.

C: The liquid has to give up heat in order for the this reaction to take place. C is the answer.

D requires heat. It is not the answer.

What property of matter does not change even though the appearance may change?
IceJOKER [234]

Answer:

The law of the conservation of mass states that matter is neither created nor destroyed, only converted to other forms. Therefore, the mass never changes, even if its appearance does.

What is the name of an immune system response to a substance in food?
poizon [28]

Answer:

The adaptive (also called humoral or specific) immune system is typically only involved in immune responses to bacteria, bacterial toxins and virus antigens. It involves the production of antibodies (also called immunoglobulins) against a specific target. The target of an antibody is called an antigen.
